-5 ≤ 3m + 1 < 4
- 1 - 1 - 1
-6 ≤ 3m < 3
3 3 3
-2 ≤ m < 1
Solution Set: {m|-2 ≤ m < 1}, {m|m ≥ -2 and m < 1}, [-2, 1)
The answer is A.
Let's make an equation where x is the number of gallons and y will be the overall price.
2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.
2.5(4)=10
So, the price of 4 gallons is $10.
Answer:
y = 5/2
Step-by-step explanation:
-4y+6<-4 subtract 6 from both sides
-4y + 6 - 6 < -4 - 6 = -4y < -10 since both sides are negative we multiply it by -1 and get ➡ 4y < 10
Now divide both sides by 4
4y ÷ 4 < 10 ÷ 4 ➡ y < 5/2
Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
Answer:
None of the options are correct, as the answer is <u>2x - 18 = 68.</u>
Step-by-step explanation:
The <u>2x</u> represents the length (x) being half of the width (68)
The <u>-18</u> represents the width (68) being 18 less than twice the length (2x)
